R2/MF Signaling
R2/MF signals that are used for supervisory signaling on the network are called line signals. Line
signals are beyond the scope of this document.
15.2 Direct Dialing-In Service
Since R2/MF address signals can provide the telephone number of the called subscriber’s line, the
signals may be used by applications providing direct dialing-in (DDI) service, also known as direct
inward dialing (DID), and dialed number identification service (DNIS).
DDI service allows an outside caller to dial an extension within a company without requiring an
operator to transfer the call. The central office (CO) passes the last 2, 3, or 4 digits of the dialed
number to the customer premises equipment (CPE) and the CPE completes the call.
15.3 R2/MF Multifrequency Combinations
R2/MF signaling uses a multifrequency code system based on six fundamental frequencies in the
forward direction (1380, 1500, 1620, 1740, 1860, and 1980 Hz) and six frequencies in the
backward direction (1140, 1020, 900, 780, 660, and 540 Hz).
Each signal is composed of two out of the six fundamental frequencies, which results in 15
different tone combinations in each direction. Although R2/MF is designed for operation on
international networks with 15 multifrequency combinations in each direction, in national networks
it can be used with a reduced number of signaling frequencies (for example, 10 multifrequency
combinations). See Table 21 and Table 22 for lists of the signal tone pairs.
